My gut feeling with io_uring is that it wouldn't help as much with messaging applications with 100 byte request/reply patterns. It would be better in a with a pipelined situation, through a load balancing front end. I would love to be proven wrong, though.

1.2M req/s means 2.4M (send/recv) syscalls per second. I definitely think io_uring will make a difference. Just not sure if it will be 5% or 25%.
